KNITTING-MACHINE TAKE-UP.

SPECIFICATION forming part of Letters Patent No. 784,567, dated March14, 1905.

Application filed August 6, 1903. Serial No 168,393-

Be it known that I, LEON O. HUSE, a citizen of the United States,residing at Laconia, in the county of Bel knap and State of New Hampshire, have invented an Improvement in Knitting-Machine Take-Ups, ofwhich the follow ing description, in connection with the accompanyingdrawings, is aspecification, like letters on the drawings representinglike parts.

My invention is an improved take-up for knitting-machines and the like,its object being to provide means or enabling the operator to adjust orremove the knitted fabric from the take-up without stopping the machine.

I have applied my invention to the usual form of take-up, comprising aframe pivoted and preferably counterbalanced and carrying rolls anddriving mechanisms therefor, between which the web or knitted article isautomatically pulled with such tension as may be required, and insteadof being obliged to stop the machine and turn back the take-up mechanismby hand, as has been the practice, I provide means for temporarilydisconnecting the take-up rolls and their driving mechanism, so that thelatter may not be interfered with in any way, and the rolls are free tomove independently thereof, as required.

Further advantages of my invention will be set forth in connection withthe following description of the constructional details thereof,reference being had to the accon'lpanying drawings, in which I haveshown apreferred embodiment of my invention, and later will be moreparticularly defined in the appended claims.

In the drawings, Figure 1 is a fragmentary detail of the lower portionof a knitting-machine, showing in side elevation my invention appliedthereto. Fig. 2 is a horizontal sectional view taken on the line 2 2',Fig. 1. Fig.

. 3 is an enlarged longitudinal sectional viewof one form ofdisconnecting device.

It will be understood that my invention is not restricted to anyparticular form of knit-v ting-machine or take-up mechanism; but forconvenience of illustration I have shown a take-up comprising a frame a,pivoted at a" to a bracket (0 mounted on a standard a of a usualknitting-machine, the further details of which are not shown. Said framea has an arm (1 extending outwardly and provided with acounterbalance-weight a, which regulates the tension or degree of pullof the take-up by counterbalancing more or less the weight 0f themechanism carried at the other end of the frame. Adjacent its pivot theframe carries an upright portion a, in which is journaled a shaft (17,provided at one end with a driving-pulley a, driven by a belt a. fromthe driving mechanism of the upper portion of the knitting-machine, andat its other end said shaft (4 is provided with a worm a meshing with aworm-wheel a, fast on a shaft (4 journaled in a cross-bar a of theframe. The latter beyond said cross-bar has two separated parts a a inwhich are journaled a pair of take-up rolls a a, the latter beingadjustable in ways a by means of adjusting-bolts (4 operating throughthe end of the frame against the journal-boxes of the roll a At one endsaid rolls are provided with similar intermeshing pinions a (1. and theroll {0 3i its opposite end has a gear (4 adapted to mesh with a pinion0 splined on shaft a and free to be moved longitudinally bya handhold oconnected thereto by a sleeve a while at its other end it is releasablylocked in normal operative position by a spring a. engaging a groovedcollar (1 secured to the inner side of said pinion a. This constitutesone form of coupling device for detachably connecting the take-u p withits driving mechanism.

In operation the take-up rolls a a are adjusted into proper engagementwith the web 20 of knitted material, which is fed down from the knittingmechanism above, and the counterbalance-weight a is adjusted out or into give the required tension according to the kind and quality of fabricbeing knitted. As the knitting progresses the driving mechanism throughthe belt a, pulley a, worm-gear a wheel a, and train of gears therefromcauses the work w to be taken up by the rolls as rapidly asitis knitted,the take-up mechanism swinging freely on its pivot a, according to therequirements of the work. If for any reason the work w requires to beslackened or removed from the take-up or tightened therein, the operatorinstead of stopping the mechanism simply lifts up on the spring a withone hand and pulls the pinion rfoutwardly with the other hand, therebyinstantly disengaging said pinion from the gear 64 leaving the rolls a"a free to turn in any direction that the work 20 may be'pulled by theoperator. If the fabric is to be slackened, the operator, havingreleased the driving mechanism from engagement with the take-up rolls,simply pulls up slightly on the work until the proper slackness issecured. The rolls a (0 when disengaged from the pinion a may be turnedfreely in either direction, and by pulling on the work the latter may bewithdrawn from the machine. The operator may reengage the drivingmechanism with said rolls simply by pushing the pinion a back intoplace, where it is locked by the spring (0 I do not intend to restrictmy invention to the particular embodiment thereof herein shown, inasmuchas it is readily applicable to various kinds of take-up and is capableof a wide variety of mechanical embodiments without departing from thespirit and scope of my invention.

If desired, (and in some instances the necessities of the work requireit,) the weight a may be used at the opposite side of the fulcrum rtfrom that shown in the drawings, the loop of the weight entering a notchta The weight will be used in the position shown by full lines where theyarn is tender and it is desired to counterbalance the weight of thetake-up; but on larger machines using heavy yarns the weight will besustained at the lefthand side of the fulcrum a close to where the workcomes from the needle-cylinder, as represented by dotted lines.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, isi 1. A take-up comprising a frame pivotallymounted, a pair of take-up rolls journaled in said frame, gearsconnecting said rolls, a crossbar carried by said frame, a shaft mountedin said cross-bar, means for driving said shaft, and a pinion mounted torotate with said shaft, and movable longitudinally thereon to carry saidpinion into and out of engagement with the said take-up rolls.

2. A take-up comprisinga pivotally-mounted frame, take-up rollsjournaled therein, a driving-shaft therefor, a pinion normally indriving connection with said rolls and mounted to rotate with and belongitudinally movable on said shaft into and out of driving engagementwith the take-up rolls, and means to rotate said shaft.

3. Atake-up comprising a pivotally-mounted frame, take-up rollsjournaled therein, a driving-shaft therefor, a pinion normally indrivingcon nection with said rolls and mounted to rotate with and belongitudinally movable on said shaft into and out of engagement with thetake-up rolls, locking means for holding the pinion in drivingengagement with the rolls, and means to rotate said shaft.

4. A take-up comprising a frame pivotally mounted to swing upward anddownward in a vertical plane, a pair of take-up rolls mounted in saidframe, a cross-bar on said frame, a driving-shaft mounted in saidcross-bar, a pinion 'splined to said shaft to be longitudinally movablethereon and rotatable therewith, to put the same into or out of drivingconnection with the take-up rolls, and means for rotating said shaft.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
